live lcd

What am I doing wrong? I have a xt20 and xt100, what setting do I use to see the subject in the lcd?

For X-T20 (and I assume the same for the X-T100):

Press the VIEW MODE button to cycle through the following display modes:

EYE SENSOR: Putting your eye to the viewfinder turns the viewfinder on and the LCD monitor off; taking your eye away turns the viewfinder off and LCD monitor on.
EVF ONLY: Viewfinder on, LCD monitor off.
LCD ONLY: LCD monitor on, viewfinder off.
EVF ONLY + : Putting your eye to the viewfinder turns the viewfinder on; taking it away turns the viewfinder off. The LCD monitor remains off.
